To all whom it may concern:

Be it known that I, JOHN S. THURMAN, a citizen of the United States, and rcsidentof St. Louis, Missouri, have invented certain new and useful Improvements in a Combined Disinfecting and Grease-Removing Apparatus, of which the following'is a specification containing a full, clear, and exact .de'sciip tion, reference being had to theaccompanyi1 e drawings, forming a part hereof! v iy inventionrelates to an. apparatus or tool for distributing a liquid or powdcred disinfectant by the use of compressed air, and said tool being so adapted to housed in the '1 5 removal of grease spots-and the like from carpets, curtains, upholstering, and the'like. The object of my invention is to provide a simple, inexpensive apparatus comprising a container for the liquid or powdered disinfectant, insect exterminator, or soa suds, and which device is readily attache to a flexible compressed air conveying tube; and there being valves conveniently located for controlling the passage of compressed air through the device, and also-the discharge of the disinfectant qr soapsuds therefrom.

To the above purposes, my invention consists in certain ndvel features of construction and arrangement of parts, which will be hereinafter more fully set forth, pointed out in the claim,and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of an apparatus of my improved construction; Fig. 2 is a vertical section taken lengthwise through the center of the apparatus Fig. 3 is a rear elevation of the apparatus; Fig. dis a vertical section taken on the line 44 of Fig. 1; and Fig. 5 isa plan view of the spray nozzle used-in 40 connection with the ap 'aratus.

Referring by numera s to the accompan'y' ing drawings :1 designates [the container or" body of the apparatus, which is in the form of a hollow cylinder, closed atthe ends by the plates 2, in the lower portions of which are formed feet 3, which support the apparatus when not in use; and formed integral with the upper portions of said plates are brackets 4, in which is arranged a longitudinally disposed pipe 5, the rear end of whichis provided with a suitable coupling 6, by means of which the ap aratus is attached to the end of a compresse air pipe 7.

Arranged in the, pipe 5 is a' self-closing valve 8, provided withan operating handle 9 the end of which occupies a position immediately above the centralportionof the'pipe y Detachably fixed on the forward end of the pipe 5"isa fiat spray nozzle 10, the orifice in which is approximately equal to the interior 6O cross sectionalarea of the pipe 5 and leading from a T 11, located in the pipe 5 adjacent the front one of the plates 9, is short vertically disposed pipe-12, in which is located a globe valve 13; and'co'nnecting the lower end of said pipe 12, with the lower portion of the container 1 is anrelbow 14.

In the top and rear portion of the con tainer 1 is an air inlet aperture 15, and nornially closing a screw threaded aperture formed in the rear one of the end plates 2 is a screw plug 16, which, when removed, permits the container to be filled.

When the device is used as a disinfecting apparatus, the container 1 is filledwith a suitable liquid or powdered disinfectant, and the compressed ,air pipe 7 is attached to the rear end of thel' pipe 5. The operator now manually engages the pipe 5, moving the apparatus to the point desired; and by' placing the thumb on the handle 9 and depressing the same, compressed air is allowed to discharge thrgbugh the tube 5 and out through' the nozzleqlO; The valve 13 is now slightly; opened arid adjusted so as to regulate thel discharge of liquid or powder through said valve, and the suction resulting from the" passage of the air through the pipe 5 draws the liquid or powder through the pipe 12 an said liquid or powder is delivered in the for of spray through the nozzle 10, and is thus forcibly discharged into cracks, crevices, and 7 through fabric, such as carpets, curtains, and

upholstery.

The air inlet aperture 15 is provided to permit air to enter the container 1 as the liquid is withdrawntherefrom.

When the device is used as a grease spot remover, the container 1 ,is filled with soapsuds, or alike cleaning compound, and when thecompressed air is permitted to discharge through the pipe 5 and nozzle 10, the soapsuds or cleaning compound is drawn from the container by suctien, and discharged directly upon the spot to be removed. If the ,105 device isused for the removal of grease spots and thelike, the discharging end of the noz-' zle is held in direct contact with the goods being acted upon, and said nozzle is moved backward and forward over the goods with a 1 10 tion, the discharge of compressed air through I the pipe 5 is accurately regulated; and by ad .an insect exterminator, by filling the conl'= pound is forcibly discharged in the form of scrubbing action, and such action,'combined with the spray of soapsuds or cleaning compound, results in a complete eradication of grease spots and the like.

The device can be advantageously used as spray at the point desired.-

The valve 8 is conveniently located to the hand of the operator, and by its manipulajusting the valve 13, the discharge of liquid or powder through the container 1 is regu- I lated.

I claim A combined disinfecting and grease removing apparatus, comprising a cylindrical container, plates closing the ends thereof, a

tube seated in the upper ends 'of the plates, which tube forms a handle for the apparatus, means whereby a flexible connection is at tached to one end of the tubular handle, a flattened nozzle arranged on the opposite end of the tubular handle, the orifice in which nozzle is approximately equal in area to the interior cross sectional area of the tubular 3 handle, a self closing valve located in the tubular handle, a tube connecting the forward end of the container with the forward portion of the tubular handle, a valve located in said last mentioned tube for controlling 4 the degree of opening of the passage there through, there being an air inlet aperture formed in the upper portion of the container,

there being an opening formed through the rear one of the end seatedin said opening.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing witnesses.
